FLUCTUATIONS OF SAMPLING IN A MENDELIAN POPULATION

Fluctuations of Sampling in a Mendelian Population.

In experimental crosses with pedigreed cultures, the observed Mendelian ratios are supposed to be due to the chance combinations of 2” kinds of gametes (n = number of allelomorphic pairs) occurring in equal numbers. The total or aggregate results may show larger or smaller deviations from the calculated ratios, but these deviations frequently lie within reasonable limits of error on the hypothe...

Mendelian proportions in a mixed population. 1908.

TO THE EDITOR OF SCIENCE: I am reluctant to intrude in a discussion concerning matters of which I have no expert knowledge, and I should have expected the very simple point which I wish to make to have been familiar to biologists. However, some remarks of Mr. Udny Yule, to which Mr. R.O. Punnett has called my attention, suggest that it may still be worth making. In the Proceedings of the Royal ...

a swot analysis of the english program of a bilingual school in iran

با توجه به جایگاه زبان انگلیسی به عنوان زبانی بین المللی و با در نظر گرفتن این واقعیت که دولت ها و مسئولان آموزش و پرورش در سراسر جهان در حال حاضر احساس نیاز به ایجاد موقعیتی برای کودکان جهت یاد گیری زبان انگلیسی درسنین پایین در مدارس دو زبانه می کنند، تحقیق حاضر با استفاده از مدل swot (قوت ها، ضعف ها، فرصتها و تهدیدها) سعی در ارزیابی مدرسه ای دو زبانه در ایران را دارد. جهت انجام این تحقیق در م...

A New Exponential Type Estimator for the Population Mean in Simple Random Sampling

‎In this paper‎, ‎a new estimate of exponential type of auxiliary information to help simple random sampling without replacement of the finite population mean is introduced‎. ‎This new estimator with a few other estimates using two real data sets are compared with the mean square error‎.
